[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The extrusion die conductive ring shown includes a conductive ring body 1 and two fiber sheets 3 installed inside the conductive ring body 1;

[0025] Multiple fiber bundles 6 are disposed between the two fiber sheets 3;

[0026] A pressure plate 2 is provided on one side of each of the two fiber sheets 3. When the extrusion die equipment is started, the current is connected to the conductive ring body 1. The current begins to be conducted inside the conductive ring body 1. A portion of the current is transferred to the fiber sheet 3 through the contact area between the conductive ring body 1 and the fiber sheet 3. The fiber sheet 3 further disperses the current to the fiber bundle 6 connected to it. Multiple fiber bundles 6 work together to enable the current to be transmitted efficiently in the network formed by the fiber bundles 6. Finally, the current is stably conducted to the corresponding components of the extrusion die equipment to provide power for the operation of the equipment.

[0027] Both ends of the two pressure plates 2 are fixedly connected to the circular outer walls of the pressure plates, and the pressure plates 2 are inserted into the conductive ring body 1. The conductive ring body 1 has multiple screw holes 15 inside, and each of the multiple pressure plates 13 has a screw 11 inside. Each of the multiple screw 11 has a screw head 14 that engages with the screw hole 15 to limit the position of the pressure plate 2. When it is necessary to repair or replace the conductive ring, first use a screwdriver or other tools to rotate the screw 11 in the opposite direction so that the screw head 14 is gradually screwed out of the screw hole 15. As the screw head 14 is screwed out, the pressure of the pressure plate 2 on the fiber sheet 3 gradually decreases. Gently remove the pressure plate 2 from the conductive ring body 1. After removing the pressure plate 2, carefully remove the fiber sheet 3 and fiber bundle 6 from the conductive ring body 1. Conduct a comprehensive inspection of the removed components, including the conductive ring body 1, fiber sheet 3, fiber bundle 6, pressure plate 2, screw 11, and screw head 14. Replace any damaged or aged parts according to the inspection results.

[0028] like Figure 4 As shown, grooves 12 are provided inside the outer walls of both the upper and lower ends of the conductive ring body 1 for the limiting blocks 13 to engage. Limiting grooves are provided inside the multiple limiting blocks 13 to limit the maximum distance of the screw head 14 to be screwed upward.

[0029] Align the limiting blocks 13 at the left and right ends of the pressure plate 2 with the grooves 12 at the upper and lower ends of the conductive ring body 1, and gently apply force to make the limiting blocks 13 snap into the grooves 12 to complete the initial positioning of the pressure plate 2. When the pressure plate 2 is removed, the screw head 14 will screw into the limiting groove. At this time, it is impossible to continue to rotate in the unscrewing direction. Then, pull the screw 11 upward to remove the pressure plate 2.

[0030] like Figure 2 As shown, multiple fixing brackets 4 are fixedly connected at equal intervals to the circular inner wall of the conductive ring body 1. Each fixing bracket 4 has a fixing plate 5 on its upper side. Each fixing plate 5 has a fixing block 9 fixedly connected to its lower outer wall. Each fixing block 9 has a fixing hole 8 inside its front outer wall and near its left and right sides to restrict the position of the fiber bundle 6. Each fixing plate 5 has a fastening bolt 7 that is inserted downward into the fixing bracket 4 on its upper outer wall and near its left and right sides. Each fastening bolt 7 has a fastening nut 10 screwed into one end to fix the position between the fixing plate 5 and the fixing bracket 4.

[0031] The fiber bundles 6 are passed through the fixing holes 8 at the front end of the fixing block 9 in sequence according to the design requirements to initially determine the position of the fiber bundles 6. Then, the fixing plate 5 with the fixing block 9 is placed on the upper side of the fixing frame 4, so that the fastening bolts 7 on the fixing plate 5 are aligned with the corresponding positions on the fixing frame 4. After the fastening bolts 7 are inserted into the fixing frame 4, the fastening nuts 10 are tightened with the help of external tools to ensure that the fixing plate 5 is evenly stressed and tightly attached to the fixing frame 4.

[0032] like Figure 1 As shown, the conductive ring body 1 is made of aluminum alloy, the fiber bundle 6 is supported by a double-layer material, the fiber bundle 6 is made of carbon fiber material, and is connected to the outer shell by compression. The outer shell of the fiber bundle 6 is made of polycarbonate material.

[0033] Aluminum alloys have good electrical conductivity, providing an efficient conduction path for current. Carbon fibers have excellent electrical properties, and their unique graphite microcrystalline structure allows electrons to conduct rapidly within the fibers. Working in conjunction with the aluminum alloy conductive ring body 1, they further optimize conductivity. The fiber bundle 6 is connected to a shell made of polycarbonate material by compression bonding. The shell meets the comprehensive performance requirements of high plasticity, fracture resistance, and mechanical strength, ensuring not only good mechanical stability but also contributing to the transfer of electrons between the fiber bundle 6 and the shell, thus optimizing conductivity.

[0034] The implementation principle of this embodiment is as follows: When the extrusion die equipment is started, current is connected to the conductive ring body 1. The current begins to conduct inside the conductive ring body 1. A portion of the current is transferred to the fiber sheet 3 through the contact area between the conductive ring body 1 and the fiber sheet 3. The fiber sheet 3 further disperses the current into the connected fiber bundles 6. Multiple fiber bundles 6 work together to ensure efficient transmission of current in the network formed by the fiber bundles 6, ultimately stably transmitting the current to the corresponding components of the extrusion die equipment, providing power for the equipment operation. When it is necessary to repair or replace the conductive ring... When removing the fiber sheet 3, first use a screwdriver or other tools to rotate the screw 11 in the opposite direction, so that the screw head 14 gradually comes out of the screw hole 15. As the screw head 14 comes out, the pressure of the pressure plate 2 on the fiber sheet 3 gradually decreases. Gently remove the pressure plate 2 from the inside of the conductive ring body 1. After removing the pressure plate 2, carefully remove the fiber sheet 3 and fiber bundle 6 from the inside of the conductive ring body 1. Conduct a comprehensive inspection of the removed components, including the conductive ring body 1, fiber sheet 3, fiber bundle 6, pressure plate 2, screw 11, and screw head 14. Replace any damaged or aged parts based on the inspection results.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
